CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant VarietyOffice (CPVO) Plant Breeder's Rights Application No. 2019/2750 filed onOct. 29, 2019, under 35 U.S.C. 119(f), the entire contents of which isincorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofSanguisorba officinalis and will be referred to hereafter by itscultivar name, ‘Red Dream’. ‘Red Dream’ represents a new Burnet, anherbaceous perennial grown for landscape use.

The inventor discovered the new cultivar, ‘Red Dream’, as a chanceseedling in September of 2017 in Rijnsburg, The Netherlands. The newcultivar was discovered in a production field of Sanguisorba ‘Arnheim’(not patented) and therefore ‘Arnheim’ is a probable parent plant.

Asexual propagation of the new cultivar was first accomplished bydivision in 2017 by the inventor in Rijnsburg, The Netherlands. Asexualpropagation by division and terminal stem cuttings has determined thatthe new cultivar is stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘Red Dream’ as a unique cultivar of Sanguisorba.

-   -   1. ‘Red Dream’ exhibits flowers that are dark red in color.    -   2. ‘Red Dream’ exhibits a floriferous blooming habit.

The likely seed parent of ‘Red Dream’, ‘Arnheim’, is similar to ‘RedDream’ in plant height and habit. ‘Arnheim’ differs from ‘Red Dream’ inhaving flowers that are smaller in size and more rose pink in color.‘Red Dream’ can be most closely compared to Sanguisorba officinaliscultivars ‘Red Thunder’ (not patented) and ‘Tanna’ (not patented). Botha similar to ‘Red Dream’ in having inflorescences that are red in color.‘Red Thunder’ differs from ‘Red Dream’ in having weaker stems that arenot held upright without support and inflorescences that are slightlymore burgundy in color. ‘Tanna’ differs from ‘Red Dream’ in having asmaller plant height, more fern-like foliage, and inflorescences thatare more pink-red in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearanceand distinct characteristics of the new Echinacea. The photographs weretaken of a one-year-old plant of the new cultivar as field grown inRijnsburg, The Netherlands and placed in a 28-cm container for thephotographs.

The photograph in FIG. 1 illustrates the overall habit and appearance of‘Red Dream’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of‘Red Dream’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘RedDream’.

The colors in the photographs are as close as possible with thephotographic and printing technology utilized and color values cited inthe detailed botanical description accurately describe the colors of thenew Sanguisorba.
